Overall Image Quality & Artifact Analyzer
Evaluate photos for heavy JPEG compression artifacts, blockiness, and quality loss. Ensure your web assets are high quality before publishing.
Detect Over-Compressed Images
If an image is downloaded, resized, and re-uploaded multiple times (like a viral meme), it suffers from 'Generation Loss', resulting in ugly, blocky JPEG compression artifacts. This analyzer scans the image for these specific 8x8 pixel block artifacts, giving you an overall Quality Score. It warns you if an image is too degraded to be used in professional marketing material.
Why Use Our Image Quality Analyzer?
- Artifact Detection: Specifically looks for JPEG blocking and color bleeding.
- Marketing Safety: Ensure your brand assets look crisp and premium.
- No Uploads: Evaluates proprietary company assets securely offline.
- Objective Scoring: Stop guessing if a photo is 'good enough'.

Frequently Asked Questions
To save space, JPEG compression groups pixels into blocks and averages their colors. When over-compressed, these blocks become visible to the human eye, making the photo look 'crunchy' or pixelated.
No, once an image is heavily compressed, that data is permanently lost. You must use AI upscaling tools to attempt a restoration.
